reporter Susan Intern Wang Mengxi
fear of hepatitis B vaccine quality problems, dare not "body test needle" ah! 1 months should be vaccinated, how 3 This is more common than the adverse reaction, and the coincidence reaction is not related to the quality of the vaccine, which is more common than the adverse reaction of Susan interns Wang Mengxi.
the domestic hepatitis B vaccine and imported vaccine are different in price, but there is no difference in the effect and safety between them.
vaccine preventable infectious diseases need to maintain a high vaccination rate in order to establish the immune barrier of the population.
by the end of 2013, many hepatitis B vaccine cases occurred in Kangtai, Shenzhen. Despite investigation and verification by authoritative departments, the quality of hepatitis B vaccine used in these cases is no problem, but the adverse effects brought by this incident are continuing to ferment. According to the data issued by the National Health Planning Commission, the vaccination rate of hepatitis B vaccine in some parts of China has dropped by 30% from the end of last year, and the inoculation rate of other vaccines has also decreased by 15%.
in recent days, a reporter interviewed found that after the incident, the number of hepatitis B vaccination in Ji'nan has also declined. Although it has gradually returned to normal, many parents have had a crisis of confidence in the vaccine.
1 [status] 1 [current] inoculation points decline 30% parents to postpone, or hit the imported vaccine for 8 days, the citizen Zou Zou took the child to the Qianfo Hill hospital to vaccinate the hepatitis B vaccine. Ms. Zou's child is 3 months old. According to the "0.1.6" vaccination principle of hepatitis B vaccine, the child should be vaccinated against hepatitis B at birth, 1 months of birth and 6 months of birth. Then why did the child come in 3 months? The doctor asked that when the child should be vaccinated for 1 months, the Shenzhen Taikang vaccine happened, and she did not dare to inoculate the children again. "
" during that time, all over the country had been exposed to the death of the children after vaccination. The death of the children in the media was too bad, so I did not dare to let the child 'test the needle', and the old man in the family stopped beating. Later, the state said that it was not the problem of vaccine quality, but the nerves of the whole family were not so intense. Ms. Zou said. In fact, many parents and Ms. Zou have the same idea.
Li Yan, director of the provincial hospital of Qianfo Hill Province, introduced that after the outbreak of hepatitis B vaccine in Shenzhen Taikang, it had an impact on the inoculation point, which was mainly the time for many parents to vaccinate their children, and more parents who were required to vaccinate against hepatitis B vaccine. "This directly led to a decline in the number of inoculated seeds within a period of time. According to statistics, the inoculation point of the inoculation point from 1 to October last year was 2670 needles, the average 267 needle per month, and from December to February of this year. After the event, the inoculation amount was 587 needles, the average of 195 needles per month and the monthly decline of 30%. Li Yan said.
later, the reporter also visited 10 hepatitis B vaccine inoculation points, of which 3 showed the hepatitis B vaccine event, the amount of inoculation decreased slightly, and the other showed no obvious change. But they are generally aware that after this incident, parents' distrust of hepatitis B vaccine has increased a lot. "Many parents will ask for hepatitis B vaccine manufacturers and origin, some parents will choose delay or direct selection of imported vaccines, parents who choose to play imported vaccines have increased significantly." Yanshan office, community health service center, a staff member.
2 [tracking] 2 [tracking] companies lost over two hundred million Ji'nan for more than 20 years of this vaccine parent's unease, in Ji'nan some wholesale business enterprises can also be reflected. At present, there are 7 wholesale and commercial enterprises in Ji'nan. The head of the quality control department of a pharmaceutical Co., Ltd. introduces that the company sells two kinds of hepatitis B vaccine to the CDC, that is, the self selected vaccine that parents can choose. "We mainly deal with hepatitis B vaccine from two manufacturers of Glaxo and Watson in Yunnan. Even though it did not run the vaccine, it felt cold. Because our hepatitis B vaccine is not mandatory in the national plan, it will be more affected. " The person in charge said.
prior to the media interview, Shenzhen Kangtai biological Co., Ltd., the person in charge said that Shenzhen Kangtai lost more than 200 million yuan in the incident.
provincial CDC preventive vaccination outpatient staff, Kangtai biology is the largest hepatitis B vaccine production enterprise in China and the world, and more than 50% of the hepatitis B vaccine provided free of charge in China is provided by Kangtai biology. Shenzhen Taikang hepatitis B vaccine is also a commonly used planned vaccine in our province, which is uniformly purchased by the Provincial Department of health. For a long time, Ji'nan has been using the vaccine of the manufacturer, and it has been used for more than 20 years. "But the vaccine is very poor and the antibody production rate is low, so some vaccines have not been used recently."
indeed, the reporter visited the more than 10 hepatitis B vaccination points, rarely found in Shenzhen Taikang hepatitis B vaccine, mostly from Dalian Han Xin and the Beijing Tiantan of the hepatitis B vaccine. "The state said that after the Shenzhen Taikang vaccine had no problem, we would dare to use it. But at the moment, some adults are fighting, and few parents are fighting for their children." A hepatitis B vaccination point in Tianqiao District, a staff member, said.
more importantly, the impact of the event is not more than the sales of Shenzhen's Taikang company, and its ripples have made the public skeptical about the safety of hepatitis B vaccine and even all the vaccines.

vaccination is not related to the quality of the vaccine. It should not be introduced by
the HBV vaccine is only the coupling reaction of vaccination. What is a coupling reaction? It happens at the same time, but it has nothing to do with it. For example, some children who have been vaccinated against hepatitis B have just had a baby rash, and parents think it is a vaccine. In fact, children's rash is caused by viruses. Vaccines do not cause rash in infants, but they are only combined. "Everyone knows that after vaccination, some children will have a low fever, allergy and other adverse reactions, but in clinical, the vaccine's coupling reaction is more common than the adverse reaction, and the coupling reaction is not related to the quality of the vaccine." Li Yan said.
Li Qiang, chief physician of Jinan Infectious Disease Hospital, said that the public should have an objective and comprehensive understanding of the vaccine and understand its advantages and limitations. Vaccine as a foreign body, any vaccine into the body, will inevitably cause an adverse reaction to other people, but the rate of adverse reactions is extremely low, not more than one millionth. The preventive effect of the vaccine is obvious to all. In the 50s and 60s of last century, the incidence of smallpox in China was very high, but the disease was quickly eliminated by vaccination. Another example is the epidemic cerebrospinal meningitis. There are tens of thousands of cases every year in seventy and 80s.
"there is no doubt that the protective effect of vaccines on human body is much larger than that of adverse reactions." Therefore, Li Qiang said, the public should not focus on less than one millionth of the adverse reaction, the vaccine to the child is still to be hit, can not choke waste.
at the same time experts remind parents that domestic hepatitis B vaccine technology is very mature and safe, can continue to inoculate, and compared to imported vaccines, but the price is different, depending on the consumer psychology, both in the effect and safety of no difference. And if the public is worried, if you want to postpone the vaccination for the children, it will be one or two months after the delay, but the delay will affect the vaccination effect.
data speak
do not vaccinate, the risk of infant infection is higher.
vaccine boycott is the most worrying thing for medical experts. In
interviews, medical experts told reporters about such an example. In 1974, there were reports of 36 severe neurological responses after vaccination against DPT vaccine (pertussis, diphtheria and tetanus three in one vaccine) in the United Kingdom. TV news continued to report the incident, and the public lost confidence, resulting in interruption of vaccination and the vaccination rate dropped from 81% to 31%. However, with the decline of vaccination rate, the incidence rate increased from nearly 1/10 million to 100/10 million 200/10 million, thus forming an epidemic of pertussis. "Not vaccinate children will not only increase their risk of infectious diseases, but also affect the establishment of a group immune barrier." Li Yan, director of the Department of child protection, Qianfo Hill provincial hospital, said that if the vaccination rate continues to decline, it may lead to the epidemic or outbreak of the vaccine directed communicable diseases. The latest data released by the State Health Planning Commission also show that if there is no hepatitis B vaccine, there will be 4.5 million newborns infected with hepatitis B every year. In order to eliminate measles, more than 95% of the aged children are required to receive 2 doses of measles vaccine; to eliminate polio eventually, more than 90% of the children must be vaccinated against polio. Other vaccines are also preventable infectious diseases. It is necessary to maintain a high vaccination rate in order to establish the immune barrier of the population.
